The remainder of the tangible assets are computers in the possession of Seller's
employees, as indicated in the records of the Seller provided by Seller to Buyer
at Closing.

      2.6 Financial Statements; Undisclosed Liabilities.
          ---------------------------------------------

          (a) Seller has previously furnished to Buyer and Parent copies of its
unaudited financial statements for the fiscal years ended December 31, 1995,
1996 and 1997 and the interim period ending February 28, 1998, which financial
statements for 1997 and part year 1998 are set forth in Schedule 2.6(a) .
                                                        ---------------
Except as described in Schedule 2.6(a), such financial statements referred to in
                       ---------------
this Section 2.6(a) were prepared in conformity with generally accepted
accounting principles applied on a consistent basis, and fairly and accurately
present the financial position of Seller as of the dates thereof and the results
of operations and cash flows of Seller for the periods shown therein (subject to
the absence of footnotes that would be required by generally accepted accounting
principles), and to the best of Seller's knowledge, are complete, correct and
consistent in all material respects with the books and records of Seller.

          (b) The projections set forth on Schedule 2.6(b) represent good faith
                                           ---------------
estimates of Seller's performance for 1998 which were in good faith believed to
be reasonable when made and continue to be reasonable as of the date hereof.
Notwithstanding the foregoing, no representation is made that the projections
will be achieved.

          (c) Except as and to the extent reflected or reserved against in the
audited balance sheet of Seller at December 31, 1997 contained in the financial
statements referred to in Section 2.6(a) (the "Base Balance Sheet") or as listed
on Schedule 2.6(c), the Seller does not have and is not subject to any material
   ---------------
liability or obligation of any nature, whether accrued, absolute or otherwise,
of a kind that would be required to be disclosed in such financial statements
or, to its knowledge, any other material liability or obligation.

      2.7 Tax Matters.  Seller has timely and properly filed all federal, state,
          -----------
local and foreign income, excise and franchise tax returns, real estate and
personal property tax returns, sales and use tax returns and other tax returns
required to be filed by it and has paid all Taxes (as defined below) owing by it
(whether or not shown on any Tax Return), except Taxes which have not yet
accrued or otherwise become due, for which adequate provision has been made in
the pertinent financial statements referred to in Section 2.6 above.  The
provision for taxes on the Base Balance Sheet is sufficient as of its date for
the payment of all material accrued and unpaid federal, state, county and local
taxes of any nature of Seller, and any applicable taxes owing to any foreign
jurisdiction (collectively, "Taxes"), whether or not assessed or disputed. All
Taxes and other assessments and levies which Seller is required to withhold or
collect have been withheld and collected and have been paid over to the proper
governmental authorities. Seller has never received notice of any audit or of
any proposed deficiencies from the Internal Revenue Service or any other
taxation authority.  Neither the Internal Revenue Service nor any other taxing
authority is now asserting or, to the best knowledge of Seller, threatening to
assert

                                       9
<PAGE>

against the Seller any deficiency or claim for additional Taxes or interest
thereon or penalties in connection therewith. The Seller is and has been since
January 1, 1993 an "S Corporation" within the meaning of Section 1361(a)(1) of
the Internal Revenue Code of 1986, as amended, and the applicable laws of the
State of Virginia.

          -------------------------------------
of the Seller arise from services actually provided in the ordinary course of
business and are to the best of Seller's knowledge, valid and enforceable claims
not subject to set-off or counterclaim. To the best of Seller's and each
Stockholder's knowledge, all of the accounts receivable of Seller are
collectible in the ordinary course of business (less reserve for bad debts set
forth on the Base Balance Sheet). Notwithstanding the preceding sentence, Seller
does not guarantee collectibility of such receivables.  Seller does not have any
accounts receivable or loans receivable from any person, firm or corporation
which is affiliated with Seller or from any stockholder, director, officer or
employee of Seller or any affiliate thereof.  Schedule 2.8 lists the accounts
                                              ------------
receivable of the Seller as of February 28, 1998.

conducted or currently contemplated to be conducted (the "Seller Rights"), which
rights are set forth on Schedule 2.9(a), provided that no representation is made
                        ---------------
with respect to "off the shelf" software used by Seller that is generally
commercially available.

          (b) The business of Seller as presently conducted does not violate any
agreements which Seller has with any third party or, to the best of Seller's or

trade secret or, to the best knowledge of Seller, any other Intellectual
Property Rights of any third party.

          (c) No claim is pending or, to the best knowledge of the Seller,
threatened against the Seller nor has Seller received any notice or claim from
any person asserting that any of the Seller's present or contemplated activities
infringe or may infringe any Intellectual Property Rights of such person, and
Seller is not aware of any infringement by any other person of any rights of
Seller under any Intellectual Property Rights.

          (d) Each current and former contract employee of the Seller involved
in development of any of the Seller Rights, has executed an agreement regarding
confidentiality and proprietary information, and, to the best knowledge of
Seller, none of such employees, consultants or independent contractors is in
violation of any agreement or in breach of any agreement or arrangement with
former or present employers relating to proprietary information.

all applicable federal, state, local and foreign laws, regulations and
guidelines, including without limitation all laws, regulations and guidelines of
the Food and Drug Administration, the Federal Trade Commission, the Federal
Communications Commission, the American Medical Association and the
Pharmaceutical Marketing Association, in each case to the extent applicable.

Seller, the ACCME of the ACPE in order for Seller to obtain full accreditation
from each of the ACCME and the ACPE.  No other consent of either the ACCME or
the ACPE is required in order for Seller's accreditation status to remain in
full force and effect following the transactions contemplated by this Agreement.
Seller has no knowledge that the current director of the Strategic Institute or
any person who was "accredited" by the ACCME or the ACPE does not plan to accept
employment with Buyer after the Closing.  Neither Seller or either Stockholder
has been:  (a) convicted in a criminal proceeding or named as a subject of a
pending criminal proceeding (excluding traffic violations and other minor
offenses); (b) subject to any order, judgment, or decree (not subsequently
reversed, suspended or vacated) of any court of competent jurisdiction

Schedule 2.12 sets forth the distributions made to Seller's stockholders for the
-------------
purpose of satisfying their obligations for 1997, and an estimate of each
stockholder's obligations for the portion of 1998 prior to the Closing, arising
out of Seller's status as a subchapter S corporation, and such distributions are

the Buyer and Parent that with respect to Seller's receipt of Parent Stock
hereunder:

          (a) Seller is acquiring the Parent Stock for its own account, for
     investment, and not with a view to any "distribution" thereof within the
     meaning of the Securities Act.  Seller is an "accredited investor" as
     defined in the Securities Act and is knowledgeable and experienced in the
     making of investments of the type involved in the acquisition of the Parent
     Stock pursuant to the Agreement, is able to bear the economic risk of loss
     of its investment in the Parent, has been granted the opportunity to
     investigate the affairs of the Buyer and Parent and to ask questions of
     their officers and employees, and has availed itself of such opportunity
     either directly or through its authorized representative; and

          (b) Seller understands that because the shares of Parent Stock have
     not been registered under the Securities Act or securities or "blue sky"
     laws of any jurisdiction, it cannot dispose of any or all of the shares of
     the Parent Stock unless such shares of Parent Stock are subsequently
     registered under the Securities Act or exemptions from such registration
     are available.  Seller acknowledges and understands it has no right to
     require Parent to register the Parent Stock except as set forth in the
     attached Registration Rights Agreement.  Seller further understands that
     the Parent may, as a condition to the transfer of any of the Parent Stock,
     require that the request for transfer be accompanied by an opinion of
     counsel as described below.  Seller understands that each certificate
     representing the Parent Stock will bear a legend in substantially the form
     provided below (in addition to any legend required under applicable state
     securities laws).

          THE SHARES REPRESENTED HEREBY HAVE BEEN ACQUIRED BY THE HOLDER NAMED
          HEREON FOR HIS OWN ACCOUNT FOR INVESTMENT; AND SUCH SECURITIES MAY NOT
          BE PLEDGED, SOLD OR IN ANY OTHER WAY TRANSFERRED IN THE ABSENCE OF AN
          EFFECTIVE REGISTRATION STATEMENT FOR SUCH

                                       17
<PAGE>

          SECURITIES UNDER THE SECURITIES ACT OF 1933, AS IN EFFECT AT THAT
          TIME, OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER
          THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

      2.25     Millennium Compliance.  All computer software products, except
               ---------------------
for commercially available software, that are owned by Seller, exclusively
licensed to Seller, licensed, sold or otherwise distributed to others by Seller
or are otherwise required for the conduct of the Business ("Software") are
Millennium Compliant.  As used herein, "Millennium Compliant" shall mean the
ability of the Software to provide the following date related functions:

               (i) consistently handle date information before, during and after
     January 1, 2000, including but not limited to accepting date input,
     providing date output and performing calculations on dates or portions of
     dates;

               (ii) function accurately in accordance with the documentation
     relating to the applicable Software and without interruption before, during
     and after January 1, 2000, without any change in operations associated with
     the advent of the new century;

               (iii)  respond to two-digit date input in a way that resolves any
     ambiguity as to the century in a disclosed, defined and predetermined
     manner; and

               (iv) store and provide output of date information in ways that
     are unambiguous as to century.

               (iv) any Claim (other than the Contract Liabilities) relating to
     the operations and assets of the Business which arises in connection with
     or on the basis of events, acts, omissions, conditions or any other state
     of facts occurring or existing on or prior to the Closing Date (including,
     in each case, without limitation, any Claim relating to or associated with
     the products or services of the Business sold or provided on or prior to
     the Closing Date, tax matters, pension and benefits matters, any failure to
     comply with applicable laws and/or permitting or licensing requirements,
     any matters

     involving Athena Efessiou and environmental and worker health and safety
     matters (provided that Efessiou and not Angelides agrees to indemnify Buyer
     and Parent for any Claim related to matters involving Athena Efessiou); and

               (v) any liability of Seller other than the Contract Liabilities.

          The rights of Buyer Indemnified Parties to recover indemnification in
respect of any Claim arising under clause (ii), (iii), (iv), or (v) of this
Section 7.1(a) shall not be limited by the fact that such Claim may also
constitute a Buyer Representation and Warranty Claim, it being understood that
the preceding clause shall not be interpreted so as to allow two separate
remedies.

          (b) The rights of Buyer Indemnified Parties to recover indemnification
under this Section 7.1 shall be subject to the following limitations:

               (i) No indemnification shall be payable by Seller or a
     Stockholder with respect to Buyer Representation and Warranty Claims or
     Claims arising under Sections 7.1(a)(ii) unless the total of all amounts
     payable pursuant to this Section 7.1 shall exceed $25,000 in the aggregate,
     whereupon the total amount of such Claims shall be recoverable in
     accordance with the terms thereof; provided, however, that such $25,000
     limitation shall not apply with respect to Claims involving fraud or
     intentional misrepresentation and provided further that any claim brought
     under Sections 7.1(a)(iii) or 7.1(a)(iv) above shall not be subject to such
     limitation if they are also Buyer Representation and Warranty Claims; and;

               (ii) All rights to indemnification with respect to Buyer
     Representation and Warranty Claims shall expire on the third anniversary of
     the Closing Date, except that Buyer Representation and Warranty Claims
     relating to or involving fraud or tax matters shall survive until and shall
     expire on the date three months after the termination of the applicable
     statute of limitations relating thereto.  Notwithstanding the preceding
     sentence, if on or prior to the third anniversary of the Closing Date a
     specific state of facts shall have become known which may give rise to a
     claim for indemnification under Section 7.1(a)(i) and a Buyer Indemnified
     Party shall have given written notice of such facts known by such Buyer
     Indemnified Party at such time to Seller and Stockholder, then the right to
     indemnification with respect thereto shall remain in effect without regard
     to when such matter shall be finally determined and disposed of.  All
     rights to indemnification under this Section 7.1 with respect to claims
     arising under Section 7.1(a)(ii), 7.1(a)(iii), 7.1(a)(iv) and 7.1(a)(v)
     shall, except as they may otherwise be extended, survive until and shall
     expire on the date three months after the termination of the applicable
     statute of limitations relating thereto.  The limitations herein with
     respect to Buyer Representation and Warranty Claims and claims arising
     under Sections 7.1(a)(ii), 7.1(a)(iii) and 7.1(a)(iv) shall not limit the
     rights of any Buyer Indemnified Party with respect to any other claims
     under this Section 7.1; and

                                       24
<PAGE>

               (iii)  Notwithstanding anything contained in this Section 7.1 to
     the contrary, Seller and Stockholder shall not be required to indemnify
     Buyer Indemnified Parties with respect to Buyer Representation and Warranty
     Claims or Claims arising under Section 7.1(a)(ii) in an aggregate amount in
     excess of $8,660,000 plus any Contingent Payment actually made (together,
     the "Indemnity Cap"), except with respect to claims relating to or
     involving fraud or tax matters, as to which no such limit shall apply.
     Until the first anniversary of the Closing, each Stockholder may satisfy
     his or her indemnification obligations to Buyer Indemnified Parties by
     delivery of shares of Parent Stock to the relevant Buyer Indemnified Party
     having a value equal to such indemnification obligations, such value per
     share to be determined by taking the average of the closing price on the
     NASDAQ National Market System for the Parent's stock for the thirty (30)
     trading days immediately prior to the receipt of such stock by the Buyer
     Indemnified Party.

      7.2 Indemnification by Buyer and Parent.
          -----------------------------------

          (a) Buyer and Parent (subject to subsection (b) of this Section 7.2)
agrees to defend, indemnify and hold Seller and each Stockholder and Seller's
subsidiaries and affiliates and persons serving as officers, directors, partners
or employees thereof (individually a "Seller Indemnified Party" and collectively
the "Seller Indemnified Parties") harmless from and against any and all Claims
(as defined in Section 1.2 hereof), whether or not arising out of third-party
claims and including all reasonable amounts paid in investigation, defense or
settlement of the foregoing, which may be sustained or suffered by any of them
based upon, arising out of, by reason of or otherwise in respect of or in
connection with:

               (i)  any inaccuracy in or breach of any representation or
     warranty made by Buyer or Parent in this Agreement or in any Schedule or
     exhibit to this Agreement or any certificate or other document delivered in
     connection with the consummation of the transactions contemplated by this
     Agreement (collectively, "Seller Representation and Warranty Claims");

               (ii) any breach of any covenant or agreement made by Buyer or
     Parent in this Agreement or in any Schedule or exhibit to this Agreement or
     any certificate or other document delivered in connection with the
     consummation of the transactions contemplated by this Agreement;

               (iii)   any Claim relating to the operation by Buyer of the
     Subject Assets after the Closing Date which arises in connection with or on
     the basis of events, acts, omissions, conditions or any other state of
     facts occurring or existing after the Closing Date (including, in each
     case, without limitation, any Claim relating to or associated with the
     products or services sold or provided by Buyer after the Closing Date,
     product liability matters, warranty claims, tax matters, pension and
     benefit matters, any failure to comply with applicable laws and/or
     permitting or licensing requirements, personal injury and property damage
     matters and environmental and worker health and safety matters); and

                                       25
<PAGE>

               (iv)  the non-performance of the Contract Liabilities to the
     extent assumed by Buyer hereunder as they become due, in accordance with
     their respective terms.

          The rights of Seller Indemnified Parties to recover indemnification in
respect of any Claim arising under clause (ii), (iii) or (iv) of this Section
7.2(a) shall not be limited by the fact that such Claim may also constitute a
Seller Representation and Warranty Claim, it being understood that nothing in
the preceding clause shall not be interpreted so as to allow two separate
remedies.

          (b) The rights of Seller Indemnified Parties to recover
indemnification under this Section 7.2 shall be subject to the following
limitations:

               (i) No indemnification shall be payable by Buyer or Parent with
     respect to Seller Representation and Warranty Claims or Claims arising
     under Section 7.2(a)(i) unless the total of all amounts payable by Buyer
     and Parent taken as a whole pursuant to this Section 7.2 shall exceed
     $25,000 in the aggregate, whereupon the total amount of such Claims shall
     be recoverable in accordance with the terms thereof; provided, however,
     that such $25,000 limitation shall not apply with respect to Claims
     involving fraud (it being understood that any claim brought under Sections
     7.1(a)(iii) or 7.1(a)(iv) above shall not be subject to such limitation if
     they are also Seller Representation and Warranty Claims).

               (ii) All rights to indemnification with respect to Seller
     Representation and Warranty Claims shall expire on the third anniversary of
     the Closing Date, except that Seller Representation and Warranty Claims
     relating to or involving fraud, or product liability matters shall survive
     until and shall expire on the date three months after the termination of
     the applicable statute of limitations relating thereto. Notwithstanding the
     preceding sentence, if on or prior to the third anniversary of the Closing
     Date a specific state of facts shall have become known which may give rise
     to a claim for indemnification under Section 7.2(a)(i) and a Seller
     Indemnified Party shall have given written notice of such facts known by
     such Seller Indemnified Party at such time to Buyer, then the right to
     indemnification with respect thereto shall remain in effect without regard
     to when such matter shall be finally determined and disposed of. All rights
     to indemnification under this Section 7.2 with respect to Claims arising
     under Section 7.2(a)(ii), 7.2(a)(iii) and 7.2(a)(iv), except as they may
     otherwise be extended, survive until and shall expire on the date three
     months after the termination of the applicable statute of limitations
     relating thereto.  The limitations herein with respect to Seller
     Representation and Warranty Claims and Claims arising under Section
     7.2(a)(ii), 7.2(a)(iii) and 7.2(a)(iv) shall not limit the rights of any
     Seller Indemnified Party with respect to any other claims under this
     Section 7.2; and

                                       26
<PAGE>

               (iii)  Notwithstanding anything contained in this Section 7.2 to
     the contrary, Buyer and Parent shall not be required to indemnify Seller
     Indemnified Parties with respect to Seller Representation and Warranty
     Claims or Claims arising under Section 7.2(a)(ii) in an aggregate amount in
     excess of the Indemnity Cap, except with respect to claims relating to or
     involving fraud or product liability matters, as to which no such limit
     shall apply.

      7.3 Notice; Defense of Claims.
          -------------------------

          (a) Notice of Claims.  Promptly after receipt by an indemnified party
              ----------------
of notice of any claim, liability or expense to which the indemnification
obligations hereunder would apply, the indemnified party shall give notice
thereof in writing to the indemnifying party, but the omission to so notify the
indemnifying party promptly will not relieve the indemnifying party from any
liability except to the extent that the indemnifying party shall have been
prejudiced as a result of the failure or delay in giving such notice.  Such
notice shall state the information then available regarding the amount and
nature of such claim, liability or expense and shall specify the provision or
provisions of this Agreement under which the liability or obligation is
asserted.

          (b) Third Party Claims.  With respect to third party claims, if within
              ------------------
20 days after receiving the notice described in clause (a) above the
indemnifying party gives (i) written notice to the indemnified party stating
that (A) it would be liable under the provisions hereof for indemnity in the
amount of such claim if such claim were successful and (B) that it disputes and
intends to defend against such claim, liability or expense at its own cost and
expense and (ii) provides reasonable assurance to the indemnified party that
such claim will be promptly paid in full if required, then counsel for the
defense shall be selected by the indemnifying party (subject to the consent of
the indemnified party which consent shall not be unreasonably withheld) and the
indemnifying party shall not be required to make any payment with respect to
such claim, liability or expense as long as the indemnifying party is conducting
a good faith and diligent defense at its own expense or the payment is required
in accordance with any settlement or adjudication in accordance with the
provisions of this Section 7.3; provided, however, that the assumption of
defense of any such matters by the indemnifying party shall relate solely to the
claim, liability or expense that is subject or potentially subject to
indemnification.  The indemnifying party shall have the right, with the consent
of the indemnified party, which consent shall not be unreasonably withheld, to
settle all indemnifiable matters related to claims by third parties which are
susceptible to being settled provided the indemnifying parties' obligation to
indemnify the indemnified party therefor will be fully satisfied and such
settlement does not involve the establishment of any obligations or limitations
applicable to the indemnified party.  The indemnifying party shall keep the
indemnified party apprised of the status of the claim, liability or expense and
any resulting suit,

                                       27
<PAGE>

proceeding or enforcement action, shall furnish the indemnified party with all
documents and information that the indemnified party shall reasonably request
and shall consult with the indemnified party prior to acting on major matters,
including settlement discussions. Notwithstanding anything herein stated, the
indemnified party shall at all times have the right to fully participate in such
defense at its own expense directly or through counsel; provided, however, if
the named parties to the action or proceeding include both the indemnifying
party and the indemnified party and representation of both parties by the same
counsel would be inappropriate under applicable standards of professional
conduct, the expense of separate counsel for the indemnified party shall be paid
by the indemnifying party. Subject to the indemnifying party agreeing to defend
the indemnified party, assuming and pursuing the defense of the claim, and
otherwise satisfying its obligations hereunder, the indemnified party shall not
unduly interfere in the indemnifying parties defense of such suit or raise
material objections to such defense. If no such notice of intent to dispute and
defend is given by the indemnifying party, or if such diligent good faith
defense is not being or ceases to be conducted, the indemnified party shall, at
the expense of the indemnifying party, undertake the defense of (with counsel
selected by the indemnified party), and shall have the right to compromise or
settle (exercising reasonable business judgment), such claim, liability or
expense. If such claim, liability or expense is one that by its nature cannot be
defended solely by the indemnifying party, then the indemnified party shall make
available all information and assistance that the indemnifying party may
reasonably request and shall cooperate with the indemnifying party in such
defense.

          (c) Non-Third Party Claims.  With respect to non-third party claims,
              ----------------------
if within 20 days after receiving the notice described in clause (a) above the
indemnifying party does not give written notice to the indemnified party that it
contests such indemnity, the amount of indemnity payable for such claim shall be
as set forth in the indemnified party's notice.  If the indemnifying party
provides written notice to the indemnified party within such 20-day period that
it contests such indemnity, the matter shall be resolved by arbitration in
accordance with Section 8.11 hereof.

      7.4 Sole Remedy.  The parties agree that the rights to indemnification
          -----------
under this Section 7 shall be exclusive of all rights of indemnification or
other remedies that any Seller Indemnified Party or Buyer Indemnified Party
would otherwise have in connection with the transactions contemplated by this
Agreement, except for Claims relating to or involving fraud, intentional
misrepresentation or the breach of Section 3.2 or Section 3.3 hereof.

      7.5 Satisfaction of Indemnification Obligations.  In order to satisfy the
          -------------------------------------------
indemnification obligations set forth in Section 7.1 above, a Buyer Indemnified
Party shall have the right (in addition to collecting directly from the Seller
and/or Stockholders) to set off its indemnification claims against any and all
amounts under the Contingent Payment (whether or not then due and payable) and
the amounts payable pursuant to Section 5.1.

                                       28
<PAGE>

      7.6 Insurance Proceeds.  The amount of any Claim for which indemnification
          ------------------
may be sought under this Section 7 shall be reduced by the amount of any
insurance proceeds received in respect of such Claim by the party seeking
indemnification.

                                   Exhibit A
                                   ---------

     The Contingent Payment described in 1.3(b) of the attached Asset Purchase
Agreement shall be made by Buyer to Seller upon the achievement by Buyer of a
minimum of Eight Million Dollars ($8,000,000) in revenues in calendar year 1998
from those projects set forth on Schedule 1.3(b) to the Asset Purchase
                                 ---------------
Agreement.  Schedule 1.3(b) sets forth the maximum amount of Revenue (as defined
below) that can be recognized by Buyer in relation to any individual project.
If the aggregate Revenue recognized for such projects is less than Eight Million
Dollars ($8,000,000), no Contingent Payment shall be due.  If the aggregate
Revenue related to such projects is more than Eight Million Dollars
($8,000,000), than the entire Contingent Payment shall be due and payable as set
forth below.  No Revenue from any projects not listed on Schedule 1.3(b) shall
count in any way toward the Eight Million Dollar target set forth above.

     Determination of the Revenue achieved by the Buyer shall be made by Buyer
based upon Buyers' and Sellers' good faith review of the audited financial
statements for calendar year 1998 and supporting financial and other information
for the Buyer following preparation thereof.  Revenue shall mean revenue that
has been achieved and properly recognized by Buyer in its financial statements
in accordance with Buyer's revenue recognition policy and generally accepted
accounting principles as applied by Buyer consistent with past practice.
